Things are changing fast, as regards cyber-security, just as in other walks of our day-to-day life. Cyber security threats are becoming more and more sophisticated in nature, and more and more cyber attacks are happening all around, even targeting government agencies and high-profile organizations. There are even instances when cyber attacks originate from people inside an organization. Cyber security strategies too are changing and are becoming real sophisticated, but the belief nowadays is that no layer of security can perhaps assure and ensure total security. There is the thought that almost everything is accessible today and any intruder can get it, despite going for the best of security measures.
